Giant cell arteritis most often affects the superficial temporal artery. Ar
terial territories such as the facial, carotid, myometrial and upper and lo
wer limb arteries may be affected. In this paper we describe the case of a
52-year-old patient with upper and lower limb ischaemia who presented with
grade III ischaemia in the left lower limb. Giant cell arteritis was diagno
sed as responsible for the symptoms. After treatment with corticoids, an an
giographic improvement was evidence after 2-year period. The low number of
reported cases, the diverse symptoms and varied course make diagnosis of GC
A difficult. Therefore, GCA must be taken into consideration in the ischaem
ia of inferior and superior limbs whether isolated or simultaneous.
